Question 1

1. What data do I need to start identifying underpriced or overpriced chargers?

Accepted Answer

Per-charger session count, kWh delivered, and revenue for a full billing cycle, plus your allocated fixed cost per site. Most charging management software and billing systems already log the first three; fixed-cost allocation is usually a one-time finance exercise.

Question 2

2. How is margin per session different from just tracking revenue per charger?

Accepted Answer

Revenue per charger ignores cost. A charger with high revenue but also high energy cost and a heavy fixed-cost allocation can carry thinner margin than a lower-revenue charger elsewhere — margin per session is what actually tells you if the price is doing its job.

Question 3

3. How often should CPOs reprice individual chargers?

Accepted Answer

A monthly review, tied to your billing cycle, with test changes held for a full cycle before reading results. Repricing more often than that mostly adds noise, not signal.

Question 4

4. Does per-charger pricing confuse drivers?

Accepted Answer

Not if it's shown clearly in-app before a session starts — most driver apps already display price per connector ahead of charging. The real confusion risk is pricing that changes mid-session or isn't visible until the invoice.

Question 5

5. How is this different from time-of-day or demand-responsive pricing?

Accepted Answer

Time-of-day pricing varies the price within a single charger across hours of the day. The diagnostic here sets the right baseline tariff per charger or per site first — the two work together, baseline before time-based variation.
